Propagation
The tiny seeds can be sown in flats than pricked out and transplanted into the prepared bed after 20 days or sown directly into a well aerated raised garden bed ensuring that they are not deeper that 20 mm (¾ in).

Note:
Generally under cultivation these plants prefer a open sunny wind protected position and grow in well-drained organic rich moist soil that is neutral to slightly acidic.
